1. The problem statement, all variables and given/known data Unpolarized light is passed through a polarizer-analyzer combination. The transmission of the polarizer and the analyzer are at 30 degrees to each other. What percentage of the unpolarized light gets through the combination? 2. Relevant equations 3. The attempt at a solution I am at a loss at to what to do. The only two equation I can think of, or find, that related to polarized light are the intensity equations: I = 1/2Io and I = Iocos^2(theta). The answer according to my review packet is 37.5 degrees... I just don't know how to begin in order to get that answer. Will someone give me a few hints? Please?
